The key is on On, but the engine is not started (short start position for the starter to turn). I turn off the dome and switch on to the training course. After that I release the foot brake. The vehicle gains speed (30km/h) Fall A I insert the first gear and let the clutch come. The car slows down to about 20km/h, while the speed is 3000 km/h. After a few seconds the engine runs. What happened? The control unit recognized the enough high speed and injected fuel that would be ignited. (roll energy would be needed as a starter) Fall B I insert the reverse gear and let the clutch come. What happens now? Does the engine now turn “wrong” around and is also supplied with fuel? Or does the control unit lock this? If the engine “back” would run I could run with the gear R forward and with the gä nsen 1-5 go backwards? Thank you for your answers waldeiche
